Rounded cluster of rose-pink star-shaped flowers. Position: full sun Soil: fertile, well-drained soil Rate of growth: average Flowering period: July to August Hardiness: fully hardy A later-flowering allium, which from mid- to late summer produces slender stems topped with a neat, rounded cluster of rose-pink star-shaped flowers. Relatively compact in habit, it can be used to add colour towards the front of the border, but it will also work well in pots or even windowboxes. Garden care: Avoid excessive moisture from late summer when dormant. Keep in mind that the foliage tends to die back by the time the flowers open in early summer.
